Samsung acernotebook 5012 wlmi dvd dual layer inconsistent reading

Hello all,

I have a slight problem which has probably been around since purchasing this laptop about 2 months ago.

  1. It has problems reading some cd’s that a 4 year old ibm laptop and a 6 year old pc can read.
  2. It detects a dvd media type +r etc but shows the disc as blank.

Firmware issue or defective?
If so, where can I get the firmware as a download, if possible?

Is Acer likely to destroy my laptop whilst repairing a defective drive?
If so, where can I get the firmware as a download, if possible?

bye
